- **Protection Modes:** Line-to-Line, Line-to-Ground  
- **Connection Type:** PCB mount (through-hole or surface mount options may vary)  
- **Standards Compliance:** IEC 61643-11, UL 1449  

### **Descriptions:**  
The **PROTEK SMS05C** is a **5V DC surge protection device** designed to safeguard sensitive electronic circuits from transient voltage spikes, such as those caused by lightning or electrostatic discharge (ESD). It is commonly used in **low-voltage applications**, including **telecommunications, data lines, and control systems**.

### **Features:**  
- **Fast response time** for effective transient suppression.  
- **High surge current handling** (up to 10kA).  
- **Low clamping voltage** to protect sensitive components.  
- **Compact design** for easy PCB integration.  
- **Wide operating temperature range** for harsh environments.  
- **Reliable performance** with compliance to international surge protection standards.  

For exact dimensions, pin configurations, or additional certifications, refer to the official **PROTEK datasheet**.

Application Scenarios & Design Considerations

Transient Voltage Suppressor

Alternative Part Number

  • SD05C --: Same 5V bidirectional TVS diode function in a similar SOD-323 package, widely available and a common drop-in replacement for the SMS05C.
  • PESD5V0S1BA --: 5V ESD protection diode with comparable clamping performance and low capacitance, suitable for replacing the SMS05C in ESD protection circuits.
  • ESD5V0S1BA --: 5V single-line ESD protection diode offering similar working voltage and surge capability, usable as an alternative with minor layout adjustment.
  • SD05C.TCT --: Same manufacturer TVS diode in the SD series with similar 5V standoff and low capacitance, commonly used as a direct functional substitute for SMS05C in ESD protection.
